目的了解南昌地区附红细胞体(附红体)的感染情况。方法用血涂片镜检的方法检测南昌地区的不同人群764人。结果南昌地区人群附红体总感染率为8.25%,不同地区的感染率差异有统计学意义(P﹤0.01)。比较男女两组之间的感染率差异无统计学意义(χ2=1.75,P﹥0.05)。年龄组比较,不同年龄组的感染率差异无统计学意义(P﹥0.05)。在各种职业人群中,农牧渔民、学生、城区企事业单位3种职业的感染率差异有统计学意义(χ2=23.43,P﹤0.01)。附红体感染率与人体健康状况有关,患有肺部疾患、糖尿病、高血压、心脏病、肾病等慢性疾病的人群感染率高于其他人群(P﹤0.05)。结论南昌地区人群中存在附红细胞体感染,主要表现为轻度感染,且具有地区、职业分布差异和与健康状况相关等特点。
Objective To understand the infection of Eperythrozoon (with red body) in Nanchang area. Methods Blood smear microscopy was used to detect 764 people of different populations in Nanchang. Results The total infection rate of red body in Nanchang population was 8.25%. The infection rates in different areas were significantly different (P <0.01). There was no significant difference in infection rates between men and women (χ2 = 1.75, P> 0.05). There was no significant difference in infection rates among different age groups (P> 0.05). Among occupational groups, there was significant difference in the infection rates of three kinds of occupations among farmers, students, and urban enterprises (χ2 = 23.43, P <0.01). The rate of infection with red body was related to human health status. The infection rate of people with chronic diseases such as lung disease, diabetes, hypertension, heart disease and kidney disease was higher than other groups (P <0.05). Conclusions There is an Eperythrozoon infection in Nanchang population, which is mainly mild infection and has the characteristics of regional and occupational distribution and health status.
